This shot has some odd JPG artifacts in it. I'm having problems with Photoshop CS6 JPG algorithm when saving files. They look fine on my computer after i save them, but whenever I upload them to ANY website I get really really odd artifacts that get embedded in the images. I don't know what's up. It happens both on my PC and mac versions.

EDIT* I found out that it appears to be a problem only with chrome. Weird.
